I can think of three ways, 'though there are probably more:

Spawn A and B from a master process, which can then tell A and B each
others tids.

Use the group server and have A and B join the same group.

(Ugly) Find out the tids of the other tasks in the virtual machine, and
determine (somehow) which one B is.  

I hope this helps,
